Water is pumped from Loch Awe to the upper reservoir, 360 m above, during periods of low energy use (such as at night). A 316 m-long dam forms this reservoir. Additionally the upper reservoir receives rainwater; tunnels have been built through Ben Cruachan to catch rain coming from all sides of the mountain. Around 10 % of the energy from the station is generated from rainwater; the rest is from the water pumped up from Loch Awe.
